Popis:	Reaction of (p-halophenyl)stibonic acid with diphenylsilanediol (in ratio 1:1) in refluxing toluene for 6 h afforded colorless crystalline products in high yields. Single-crystal X-ray structural elucidation reveals the formation of the products [(p-Cl-C6H4Sb)4(O)4(Ph2SiO2)4] (1) and [(p-Br-C6H4Sb)4(O)4(Ph2SiO2)4] (2), respectively. The clusters 1 and 2 were isostructural; the core consists of a distorted Sb4O4 cubane framework with the siloxides acting as bridging ligands across the antimony atoms present at alternate corners of the cube.
